Cables are designed for transmission of signals to control devices applied for operating mechanisms remote control and for inter-device connection with up to 600 V alternating voltage and 400 Hz frequency or 1000 V direct voltage.

УХЛ1 and ХЛ1 climatic modifications under GOST 15150 for other cables. Temperature range for УХЛ1: from -40°С to +70°С; for ХЛ1: from -50°С to +70°С

Cable models and their definitions shall correspond to the details given in the table below:

STRAND:insulated conductors are stranded by pairs with not more than 80 mm lay. Insulated conductors differ in color of insulation from each other in each pair. Insulated conductors, shielded cable pairs with individual shielding or unshielded pairs shall be stranded into core by lay or bunched stranding. Each lay-up of the core shall have two meter pairs or conductors different in color from each other and from other conductors or pairs of the lay-up. Meter pairs shall be located near each other. Parallel pair lay is allowed.

WATER-BLOCKING TAPE:stranded conductors of shielded or unshielded pairs are covered with water-blocking tape with separator.

SHIELDING:stranded cable pairs with individual or composite shielding shall be shieldedbefore stranding. Shielding can be made in form of copper or tinned copper wire shielding braid with a diameter of not more than 0.20 mm for cables with up to 0.75 mm² area and not more than 0.26 mm for cables with over 0.75 mm² area and not less than 65% coverage; or in form of aluminoflex braiding and contact wire of tinned copper wire with a diameter of not less than 0.4 mm. It's allowed to lay polyethylene terephthalate film under shielding on the stranded pairs. Shielding type is designated as an index (Э - aluminoflex; Эм - copper wire braiding; Эл - tinned copper wire braiding).

CORE WRAPPING:core wrapping of PVC compound is laid over water-blocking tape (for cables with no foil shielding) or over foil shielding (for cables with foil shielding) of the cables with wire armor; for нг(А)- LS and нг(А)-FRLS modifications - of flame-retardant PVC compound with low gas and fume emission. For ХЛ1 climatic modification - PVC compound shall be frost-resistant.

ARMOR:galvanized steel wire armor of 0.3 mm diameter is laid over core wrapping of armored cables. Armor coverage is not less than 60%.
